The combination of NC machine reamer and hydraulic, high precision clamping or shrink fit chuck respectively offers highest concentricity and process reliability for the produc-tion of holes to required tolerances. NC machine reamers are similar to DIN 212 with straight shank (h6) for standardised tool clamping in hydraulic or shrink fit chucks. Short delivery for intermediate sizes.

• Cutting speed too low• Worn cutting edges • Crumbling on cutting edges• Build up on cutting edges• Position to pilot hole incorrect• Insufficient lubrication

• Pre-drilled hole misaligned• Concentricity bevel lead incorrect• Apply floating holder if necessary• If necessary pilot drill to correct

predrilled position

• Cutting speed too low• No/insufficient lubrication. Cutting edge build-up.• Tool damaged, i. e. broken cutting edge• Material has a tendancy to cause build up on cutting edges.• Concentricity bevel lead incorrect

• Tool knocks in spindle• Bevel lead incorrect• Axis shifting between tool and predrilled hole. Application of floating holders• Pre-machining inaccurate

• Position to pilot hole incorrect• Back taper incorrect • Circular lands too wide• Pre-drilled hole is too small• Bevel lead blunt/ground unevenly• Feed rate too high• Chip congestion – increase feed rate to produce shorter chips

• Feed too low• Cutting edge build-up• Grease content in coolant too low• Circular lands too small• Stock removal allowance insufficient• Tool incorrectly clamped in tool holder• Machine spindle not concentric

• Reamer blunt. Does not cut, scrapes• Cutting speed too low• Component is thin-walled, springs back• Insufficient stock removal allowance, tool seizes in hole• Hole is not round due to distortion

• Tool diameter too large• Cutting speed too high• Concentricity error of machine spindle• Bevel lead of tool too short/uneven• Cutting edge build up due to wrong cutting speeds or poor lubrication• Lubricating agent unsuitable, holes too large due to lubrication

Holes too large

Unsatisfactory surface finish

Reamer seizes and breaks

Conical hole malformation

Hole has chatter marks

Holes too small

Misalignment of hole

Feed scoring marks in hole

Adapted cutting speed, an appropriate feed rate and good cooling and lubricating agents should always be a top priority for reaming operations. A further point to be considered is that the reamer always follows the direction of the pre-drilled hole. An exception is the machine bottoming reamer or a very small reamer. Consequently reamers do not correct alignment errors of predrilled holes. Errors between the spindle axis and the axis of a pre-drilled hole can be adjusted with the aid of floating holders. The following fault finding chart will be found useful in tracing the cause of some common reaming problems.

Wording:Desired dim. Required finish dimension of bore hole, defined as max./min. dimension of tolerance zoneReaming dim. the finish dimension reached in fact„Bore hole" The reached bore hole after reaming

General remarks for the determination of manufacturing

tolerances for reamers

The manufacturing tolerances to DIN 1420 are allocated tocertain tolerance zones of the holes to be reamed. Generallythey ensure the positioning of reamed holes within the relevanttolerance zone as well as the most economical use of thereamer.It must, however, be taken into account that the size of thereamed hole depends, in addition to the manufacturing toleranceof the reamer, on various other factors, such as angles of cutting edges; bevel lead of reamer; clamping of the workpiece; the tool holder; condition of the machine; the coolant and on the material of the workpiece. Therefore, from time to time other manufactu-ring tolerances than IT7 (H7) might prove more advantageous.However, in the interest of economic production and storage,it is recommended that non-standard manufacturing tolerancesare used only in exceptional cases.For determing the manufacturing tolerances the following well-proven basic rules were stipulated:

Determination of perm. max. and min. sizes of reamers

The largest permitted reamer diameter ranges at about 15% ofthe approximate hole tolerance (0.15 IT) below the permissiblemaximum diameter of the hole (see fig.), whereby the value0.15 IT will be rounded of to the next higher integer or halfμm-value, so that even μm values are derived for d1max. Thepermissible smallest reamer diameter d1min ranges at about35% of the approximate hole tolerance (0.35 IT) below thepermissible maximum diameter d1max (ex. 1).

reamer dimensions

In order to facilitate calculations, the table on page 47 indicatesthe upper and lower tolerance limits on the nominaldiameter d1 for the most common “H” tolerance zones. Withthe aid of these tolerance limits the permissible maximum andminimum reamer dimensions can be calculated.

For the designation of reamers the ISO abbreviation for thetolerance zone of the hole is indicated after the nominaldiameter. Designation of a reamer with nominal diameterd1 = 20 mm, for hole tolerance H 7:

reamer 20 H 7 DIN ...(” ... “: for DIN no. indicationof appropriate reamer)

In special cases, reamers are ordered with maximum andminimum dimensions deviating from this standard, the ISOabbreviation for the hole tolerance zone must be replaced

by the upper and lower tolerance limit of the reamer in μm,e.g. for a reamer with a nominal diameter d1 = 20 mm, uppertolerance limit = + (p) 25 μm and lower tolerance limit= + (p) 15 μm: reamer 20 p 25 p 15 DIN ... The designation shows a ‘p’ instead of the plus and an ‘m’instead of the minus sign, because »+« and » – « cannot bewritten on all machines, particularly not on data processingmachines.

The reamer is the most commonly used tool for theproduction of holes true to form and tolerance with highsurface quality. The latter meets the requirement of ‘finishing’or ‘fine finishing’ i.e. from approximately Ra 0.2 to 6.5 μmaccording to the scales laid down in DIN 4766. However,finishes to Ra = 0.5 μm can be regarded as satisfactory.Generally, the achievable tolerance ranks at IT 7. In specialcases IT 6 or even IT 5 are possible, provided that the reameris appropriately ground and all other operating conditionsmeet the high specifications.

In preparation for the reaming process, holes have to bepre-drilled and normally core drilled (fig. 1). Pre-drilled holesproduced with gun drills, are due to their highly compressedsurface, not particularly suitable for reaming. Moreover, holesproduced with gun drills show generally excellent toleranceson fit and surface qualities, so that additional fine finishing isusually not required. Should any further information on ourgun drills be needed, please do not hesitate to contact us.

Which reamer for which purpose?

With regard to their application we differentiate between:• hand reamers• machine reamers

Hand reamers

Hand reamers are turned in the hole by means of a tapwrench which is mounted on the square. The feeding actionis produced manually. Because of the low cutting ratesthese tools are made of HSS. To ensure a proper guidancein the hole the taper lead length of hand reamers is madeconsiderably longer than that of machine reamers. Handreamers are available for both cylindrical and tapered holes.

Machine reamers

Machine reamers are - as the name implies - exclusivelydesigned for use on machines and differ with regard to thetype of tool material. Due to the possibility of higher cuttingvalues, these tools are available in HSS-E, solid carbide orcarbide-tipped (fig. 5). The tool material should be selected inaccordance with the material to be machined.

Hand reamers to DIN 859 may be adjusted within theelasticity tolerance range of hardened HSS. This correspondsin practice to 1% of the diameter, i.e. for example 0.1 mmon a reamer with 10 mm diameter. In the fully expandedcondition these tools are not very resistant to breakage andmust therefore be protected against impact. They should bestored with the tension released. Expanding reamers can be adjusted over a much largerrange, even up to a few millimeters! For accuracy reasonssetting must be carried out with a ring gauge. A basic rule for reaming by hand: turn the tool only inthe cutting direction, i.e. never reverse the tool contraryto standard practice in thread cutting. Cutting edges willbecome immediately blunt if the reamer is turned back.

Carbide reamers offer the following advantages:

• Higher cutting speeds and feed rates.• Most economic machining of materials of over 1200 mm2 tensile strength.• The tool life is much higher than that of HSS-E reamers.

Reamers with special form

Reamers with special form and to special tolerances haverecently become more and more common place. Theirmanufacture requires a great deal of know-how as well asthe most modern and sophisticated tooling. We have all themachines and the knowledge to produce even the mostcomplicated tools very economically. Leave the machiningproblems to us. To meet and overcome them is the daily taskof our engineers. They are ready to assist you at all times, tofind the best possible solution and, if necessary, to arrangefor an obligation-free demonstration of our tools on your ownmachines.

A further distinctive feature of hand and machine reamers isthe geometry of the cutting section, standardised under thefollowing headings: • straight-fluted reamers• LH spiral reamers• reamers with quick spiral (45°) left-hand flutes Tools with right-hand spiral flutes are only applied in specialcases. They produce, as do twist drills, a chip flow up theflutes, which often results in an unsatisfactory surface finishquality. Reamers with straight flutes are suitable for the machiningof blind holes. Here again the absence of chip space at thebottom of the hole means that swarf must be evacuatedup the reamer flutes. For all other machining tasks, andparticularly for interrupted holes (e.g. holes with keyways,intersecting holes and the like), reamers with left-hand spiralflutes are much more suitable. Chip removal is always in thedirection of the feed and for this reason this flute geometry isused almost exclusively for through holes. Their application inblind holes is limited to tasks where reaming to the full depthis not required, so that sufficient space for the chip volumecreated is available.

The 45° LH quick spiral reamer (fig. 6) has been well tried andtested in long-chipping materials. For absolutely straight andprecisely located deep holes we recommend our machinebottoming reamers (fig. 7). Their bevel lead is face-cutting,i.e., they do not cut in conformity with the pre-drilled hole,but correct it truly to size. Machine bottoming reamers shouldalways be applied with bushings.

Accuracy in surface quality and form is tremendouslyimproved by dividing the machining process into rough andfinishing reaming. Stepped machine reamers (fig. 8) performthese two operations in one pass.

Badly worn taper pin reamers can be salvaged byresharpening of taper and reduction of circular land width.

Storage of reamers

Reamers are finishing tools and therefore very vulnerable. Toavoid damage, individual storage and transport in our plasticsleeves is recommended. Tools reward careful treatmentby producing excellent results and giving much higheroperational life.

Expectable tool breakage byoverstretching and un-screwing.

Blind hole or through hole

Straight-fluted reamers are gene-rally applied in blindholes as they, due to their cutting edge geometry, evacuatethe chips from the hole against the direction of the feed.Spiral reamers are preferred for the application in throughholes because the spiral evacuates the chips from the hole indirection of the feed.

Interrupted holes

Spiral reamers are preferred for the application in interruptedholes because the cutting edge geometry, in comparison tostraight-fluted tools, possesses a lesser tendency of grabbingon the oblique hole. If the oblique hole is > 0.25 x D, spiralreamers can also be applied in blind holes.

Stock removal allowance of the pre-drilled hole

In the event of the stock removal allowance of the pre-drilledhole exceeding the standard stock removal allowance (seetable „Recommended stock allowance“ on page 47), a quickspiral reamer or a machine bridge reamer should be applied. Itis possible to machine a considerably larger stock removal al-lowance with these tools, however, they should not be appliedin blind holes due to the bevel lead length and the spiral angle.

Expanding reamers

Expanding reamers can only be expanded. Subsequently, ifthe resulting measurement is too large it is not possible to turnthe screw back as the pretension of the tool would be lost.In most cases this leads to tool breakage. If the pre-tensionhas been taken from the tool, it requires re-adjusting and re-grinding.

Positional accuracy of the hole

A machine bottoming reamer often provides the best solutionwhen optimal positional accuracy is required, thanks to its spe-cial chamfer lead the ‘wander’ of the tool is minimal. In addi-tion, machine bottoming reamers are often applied when thepre-drilled hole and the reamer are not on the same axis (slightmisalignment).
